I've tried, but she never responds promptly. I really want her to get in contact with me, because I have to talk to her about her ignoring me. I don't want to bother her, so I need her to contact me first.
You can try to use the law of attraction to assist you with this see it as you wish it to happen and think positively. In most cases trying to contact someone though methods such as these unless you and they are both quite advanced in energy workings and the astral its a waste of your time.
If however for future information you wish to try to learn to open your telepathic channels. The process involves much study, practice, and dedication as well as your third eye to be open. This is likely far beyond the scope of your abilities so far but would be the only thing I could think of that would be actual magic of this kind.
A great link to info on telepathy.

Please note all of the info on that site is not trustworthy for the simple fact it has fluffy topics such as Invisibility and Teleportation. Although for me and my own personal success telepathy has proven to be true. "test all things and hold to that which is true"
It seems like everything in my life is waste of time.
the law of attraction has done nothing for me. I'm so desperate for contact from this person, I'm ready to sell my soul. But of course, any "solution" is impossible.
I'm ready to sell my soul.
==========================
do not have to do it!
a year ago, I made a ritual of soul selling. (for my client). but it was not for sale, and the ritual sharing of the soul for love.
This is very scary and complicated ritual. I have hardly ever agree to do so, will not even do it for money.
Life is a blessing and a gift, the actions that you take in it are upto you. Thus far it sounds like you have tried the old quick and easy spells but have yet to put in study into what magic actually is and its capabilities and are looking for a harry potter type magic. Your own words suggest you attract exactly what you are looking for, the way the law of attraction sees saying "the law of attraction does not work for me and everything is a waste of my time" is the equivalent of saying I don't want good to come into my life and I want my time wasted. I understand where you are coming from and am not trying to make light of your situation in the lest but rather inform you what I know and hope you can find a method to contact your friend.
